I'm new here, so if i make something wrong please tell me how to do!
I'm currently working on a mapping between FHIR and another internal medical data protocol. For this purpose i need to understand the utilisation of some extension like birthplace, nationality and other! I'm not sure i understand correctly with documentation provided on the fhir documentation website. In fact i would like some example to be sure i understand clearly the utilization of such extension to be able to map them correctly.
So my question is: Do you know where i can find examples for extension use, particularly for these two extension cited previously? If not can you tell me if this utilization would be correct:
> <extension xmlns="http://hl7.org/fhir" url="http://hl7.org/fhir/StructureDefinition/patient-nationality" >
> <extension url="code">
> <system value="?????">
> <code value="Bel">
> <extension xmlns="http://hl7.org/fhir" url="http://hl7.org/fhir/StructureDefinition/birthPlace" >
> <type value="both"/>
> <line value="534 Erewhon St"/>
> <city value="PleasantVille"/>
> <district value="Rainbow"/>
> <state value="Vic"/>
> <postalCode value="3999"/>
> <start value="1974-12-25"/>
Many thanks in advance for your help!
